I am facing issue while trying to upload bulk amount of product to my magento site. I have 1M product in a csv format, but I split the file in several csv files including 10k data in each file. But when I am trying to import the file after a while shows 503 server unavailable error. After trying several times I split the files into more smaller pieces where only 500 rows available. But still facing the same issue.
Please suggest.
